Small organic molecules known as electron carriers, commonly referred to as electron shuttles, are essential for cellular respiration.
Their name accurately describes what they do, which is to transfer electrons from one molecule to another.
NADP+:
The cofactor nicotinamide adenine dinucleotide phosphate, also known as NADP+ or TPN (triphosphopyridine nucleotide), is employed in anabolic activities including the Calvin cycle and the synthesis of lipids and nucleic acids, which need NADPH as a reducing agent (or "hydrogen source").
All types of cellular life use it.
The diminished version of NADP+ is NADPH.
NADP+ is, in fact, an electron carrier.
In oxidation-reduction reactions, it takes electrons and is reduced to NADPH.
It has a role in a variety of metabolic activities, including photosynthesis.
